Abstract
The spectral density A(k,ω) for the three-band Hubbard model is calculated using quantum Monte Carlo data. The states closest to the Fermi energy are related to the Zhang-Rice singlet and exhibit a bandlike behavior for a doping δ=0.25. At this hole concentration we find quantitative agreement for both the Fermi velocity and the location of the Fermi surface, when compared with angle-resolved-photoemission data.Keywords
